The 2-engine Cordership is a diagonal c/12spaceship that was discovered by Aidan F. Pierce on December 31, 2017.[1] It is the Cordership that uses the fewest number of switch engines known to be possible, as well as the smallest Cordership in terms of population, and the smallest engineered spaceship.

Bell further built two different period 96 c/12 forward rakes, one using the the 4-engine rake, along with the 2-engine Cordership and an older 3-engine block puffer,[12] the other using a new Cordership boat and block puffer, two 2-engine Corderships, and a sideways rake, both on January 6th, 2018.[12] He also built a different Cordership made from a two-engine boat puffer and a 2-engine Cordership that contains a glider which can escape if the boat is deleted by a sideways or forward glider.[12]
